Abstract: 697,066. Electric motors. TASTES, M. DE. Nov. 13, 1951 [Nov. 14, 1950], No. 26513/51. Class 35. A motor has a rotor carrying a primary winding intermittently excited by D.C. and a secondary winding having a switch device, the air gap between the rotor and stator being of variable width depending upon the position of the rotor. Fig. 1 shows a motor having a stator S having the inner periphery made up of two cylindrical segments AD, BC and of two spiral segments AB, CD. The rotor R carries a primary winding L intermittently excited by D.C. from a oommutator T and a secondary winding l the circuit of which is closed by a switching device which operates in such a way as to cause the winding l to collect by induction the break current energy of the primary winding L. The commutator T comprises a slip-ring b and an insulating ring carrying two contact segments m-w.

The D.C. to a particular primary winding is interrupted each time the rotor reaches the zone of narrowest air-gap. The rotors are shifted angularly relative to one another so that only one rotor is excited at a time.

Title: Improvements in or relating to the preparation of basic lead salts of 2:4 dinitro-resorcinol
IPC: C07C205/23
Filed: 1946-09-04
Abstract: Monobasic lead 2,4-dinitroresorcinate is made by adding a solution of a soluble normal lead salt at raised temperature to a solution of 2,4-dinitroresorcinol in an aqueous solution of a water-soluble base, the amount of base being 75 to 95 per cent of the amount calculated for the monobasic salt.  The precipitation is carried out by introducing a stream of the solution of the normal lead salt into the solution of 2,4-dinitroresorcinol at a temperature not below 70 DEG C.  For example, for each mol of 2,4-dinitroresorcinol there may be used 3 to 3.6 or 3.8 mols. of sodium hydroxide and 2 mols. of lead nitrate.  The product has a reduced tendency to gelate nitrocellulose and is suitable for use in electric fuseheads.  Specification 616,454 is referred to.

Title: Improvements in atomic precession magnetometers
IPC: G01R33/24
Filed: 1958-08-19
Abstract: 863,285. Magnetic tests. VARIAN ASSOCIATES. Aug. 19, 1958 [Oct. 14, 1957], No. 26687/58. Class 37. In a magnetometer of the type in which aligned atom portions are allowed to precess freely in a magnetic field to be measured, the frequency of their precession indicating the field strength, the sample is contained in a number of similar coil sections so connected that the currents induced by the atomic precession are additive while currents produced by disturbing fields are subtractive. The general type of magnetometer is shown in Fig. 1 in which a sequencer 13 connects a polarizing current to coil 12 to align the magnetic moments in sample 11. The sequencer then connects the coil output to amplifier and limiter 16, 17 and to a precession signal counter 18 which opens a gate 19 when the first cycle is counted. The gate allows a standard frequency from source 21 to pass to converter 22 and thus standard pulses are counted, the count ending when counter K has counted a predetermined number of precession cycles. The number of standard pulses counted is a measure of the precession frequency and is recorded at 23. Coil arrangement (Figs. 3, 4, 5). In the coil arrangement shown in Fig. 3 two sections 24, 25 of the detecting coil are mounted above each other and connected as shown. Their polarizing fields are thus in opposite directions but the induced currents add in the output. Currents induced by external fields P, however, tend to cancel each other out. In the arrangement of Fig. 4, the coils are mounted side by side and such an arrangement is shown in greater detail in Fig. 5 where the two coil sections are cemented side by side and are placed in a hollow liquidtight phenolic e.g. cylinder 28 which also contains kerosene. An electrostatic shield is provided inside the cylinder and a cushioned flooring 28<SP>1</SP> of cork is provided. In a further arrangement (Fig. 6, not shown) sixteen coil sections are mounted to form a square, alternate sections being connected in a bucking fashion.

The adjustment member 10 of a wobblertype pump feeding an hydraulic motor is actuated, in opposition to a fluid loading on a piston 16 and to the fluid reaction on the pump plungers urging the wobbler towards zero displacement, by fluid under pressure delivered to a piston 13 under the control of a valve 25 operated by a governor 28 driven by the motor. The pressure ratio across the valve 25 is maintained constant by a valve 39 which controls an outlet 40 to drain and is subject on its upper, larger-area surface 43 to the pressure in a conduit 20 between the valve 25 and the piston 13 and on its lower, smaller-area surface 44 to the pressure delivered by a pump 32 to the valve 25. The arrangement avoids speed droop since the action of the valve 39 ensures that the valve 25, after a disturbance, always returns to the same predetermined position.

Title: Variable Message Displays
Inventor: BROOKS WILLIAM
IPC: G09G3/04
Filed: 1967-06-09
Abstract: 1,194,042. Displays: shift registers. W. BROOKS. 9 June, 1967 [13 June, 1966], No. 26772/67. Heading G4H, G4C. The stages of an electronic shift register control respective display elements by means of silicon-controlled-rectifiers. In the shift register of Fig. 7, having data input at 86, shift pulses at 90 reset transfluxors 71-77 to "zero". Those not already at "zero" charge following capacitors 94 to set the respective next transfluxors to "one". Each cycle of an oscillator 70 non-destructively reads out the transfluxor state via silicon-controlledrectifiers 61-67 to lamps 11-17. In the shift register of Fig. 8, an input of "one" at 104 causes silicon-controlled rectifier 131 to fire, lighting lamp 111, discharging capacitor 161 and charging capacitor 141. A shift pulse opening switch 103 cuts off S.C.R. 131 so that capacitor 141 starts to discharge via lamp 111. The shift pulse ends before this discharge has proceeded far whereupon capacitor 141 charges capacitor 161 causing siliconcontrolled-rectifier 132 of the second stage of the register to fire. The next shift pulse cuts off both S.C.R's 131, 132 and so on. Had the input at 104 been "zero", S.C.R. 131 would not have fired, capacitor 141 would not have charged so it could not subsequently discharge to fire S.C.R. 132 via capacitor 161. The "lamps" above may each be a bar consisting of several neon tubes or a single fluorescent lamp, the bars being arranged in a figuregram or &c. to permit a selected numeral or letter or &c. to be built up by energizing selected bars. Alter natively, the lamps may illuminate respective masks for optical projection on to a screen. A row of figuregrams may be controlled ,by respective shift registers connected in series. Alternatively, each row of an elongated matrix of individual lamps may be controlled by a respective shift register to allow a message to be displayed and moved along. The data and shift input switches 86, 90, 104, 103 may be controlled by stepping switches or other shift registers. Input may be manual or on punched tape or cards. Blue, green and red lamps may be used at each lamp position and scanned in sequence.

Abstract: A wear-resistant material consists of a continuous matrix of an electrodeposited metal, preferably Ni, Co, Fe or Cu, but generally any metal with a melting point above 150  DEG C. and having a standard electrode potential of less than +0.8 volt, i.e. including Zn, Cr, Cd, In, Sn, Pb, Sb, Ag, Pd, Pt, or Au, throughout which a particulate mica, e.g. muscovite, paragonite, lipidolite, phlogopite, or biotite, having a mean major diameter greater than 5 microns, is dispersed. The material can be deposited on an electrically conductive surface, e.g. Al, Fe, steel, brass, Cu or Ni, from an electroplating solution of the metal throughout which the particulate mica is dispersed, preferably maintained by agitating the solution. The mica particles preferably have a mean major dimension between 5 and 45 microns.  For nickel plating, a bath containing nickel chloride, fluoborate and sulphamate with boric acid may be used.  The coating deposited preferably contains 1-20% by weight of mica. A poor adhering surface such as stainless steel or a graphite covered surface may be electroplated, and the electrodeposited metal containing mica subsequently stripped off as foil.  An example describes the coating of a cast aluminium alloy disc consisting of 3% Cu, 9% Si with balance Al, which is cleaned prior to electroplating first in an alkali to blacken it, then dipped in a solution containing HNO3 and HF, rinsed in water, placed in a bath containing ZnO in NaOH, rinsed in water, then in 5% H2SO4 solution and again in water.
